T all whom it may concern:

Be it known that l, Fannniucx YOUNG, subject of the King of GreatBritain, and a resident of Denver, in the county of Denver and State ofColorado, have invented a new and Improved Adjustable lllllkmOCli, of

which the following is a full, clear, and exact description.

This invention relates to adjustable nut looks, and more particularly tosuch as are constructed independently of the nuts themselves, and eachof which in general consists of an externally threaded sleeve adapted tobe slidably carried on the threaded end of a bolt, and having slotsextending longitudinally thereof, an internally threaded ring adapted tobe removably arranged on the sleeve and being provided with transverselyextending key-ways, and means adapted to be passed through the key-waysof the ring, the slots of the sleeve, and an opening in the bolt wherebythe ring and sleeve will be firmly secured in place, and will preventthe displacement of the nut against which the sleeve abuts.

The object of the invention is to provide a device of the classdescribed, simple and ellicient in construction and inexpensive tomanufacture, which can be easily arranged on a bolt to hold a nut inplace, and which is so constructed that, should it be necessary, it canbe constantly adjusted as the objects that are held in place by the nutbecome loose through wear.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation having parts in section, and showing anembodiment of my invention applied to the threaded end of a bolt; Fig. 2is a cross section on the line of Fig. 1; Fig. 3 is a perspective viewof the ring; Fig. 4 is a perspective view of the sleeve; Fig. 5 is aperspective view of a modified form of ring and Fig. 6 is a longitudinalsection of a modified form of sleeve.

In the specific form shown in the drawings, 1 represents a bolthaving athreaded end 2, on which correspondingly threaded nut 3 of any common orpreferred form, is removably arranged. The threaded end of the bolt hasan opening 4 extending therethrough. Adapted to be slidably andremovably received by the end 2 of the bolt is an annular externallythreaded sleeve 5, the

latter being provided with a plurality of longitudinal slots 6 which,when the sleeve is in a certain position on the bolt, are adapted toregister with the opening l. The sleeve is further provided with severalrecesses 7 in its upper edge, these recesses serving to allow the sleeveto be held iirinly in place by means of a suitable tool, as the deviceis being adjusted. 1 further provide an internalhx threaded ring 8annular in form and adapted to be removably arranged on the sleeve 5.The ring is provided with keynvays 9 which extend partly around the sameand which, when the ring is in position on the sleeve, will registerboth with the slots of the sleeve and the opening in the bolt. Adaptedto be passed through these registering openings is a cotter pin 10 orthe like, which serves to lool: both the ring and the sleeve firmly inplace on the bolt end.

In the modified form shown in Fig. 5, l have provided an internallythreaded ring 11 presenting key-ways 12 and having its outer facehexagonally-shaped, so that it may be easily grasped by a tool, such asa wrench or the like.

In the other modification shown in Fig. 6, l have provided a sleeve 13presenting longitudinal slots 14, the latter, however, extending onlypart way between the upper and lower end thereof, while in the preferredform shown in Fig. 4, the slots 6 extend from a short distance below thetop through the bottom.

in the operation of the device, the sleeve is arranged on the bolt endso that its upper side will rest against the nut 3 to be locked inplace. While in this position, it is held in place by means of asuitable tool, which engages the recesses 7, then the ring 8 is arrangedthereon. l i hen the ring has been properly adjusted, the pin 10 maybepassed through the key' ays, the slots of the sleeve. and the opening inthe bolt end, t ins locking the device firmly in place, the sleevecontinuing to abut against the nut.

My device is of particular advantage, for, should the nut or the objectsthat it holds in place, become worn and it should be necessary to changethe position of the nut on the bolt end, the sleeve can readily beadjusted so that it will continue to be in engagement with the nut,while there will be no necessity of boring a further opening through thebolt end to permit of this adjustment.

Having thus described my invention, 1

claim as new" and desire to secure by Letters Patent:

1. A nut lock comprising a member adapted to be loosely carried by abolt end, said member having openings extending therethrough, a furthermember adjustably arranged on said first member and being provided withopenings, said members being adjustable so that their openings willregister with an opening in said bolt end, and means adapted to belocated in said openings for locking said members in place.

2. A nut lock comprising a sleeve adapted to be removably carried on theend of a bolt, said sleeve having openings therethrough adapted toregister with an opening in said bolt end, a ring provided with openingsand adapted to be arranged on said sleeve, and a member adapted to bepassed through said registering openings to lock said ring and saidsleeve in position said member being received by said openings of saidring.

3. A nut lock comprising an externally threaded sleeve adapted toberemovably arranged on the end of a bolt, said sleeve having slotsadapted to register with an opening in the bolt end, an internallythreadsleeve and said ring are removably secured V in place.

4. A nut lock comprising an externally threaded sleeve adapted to beremovably ar ranged on the end of a bolt, said sleeve having slotsextending longitudinally thereof and adapted to register with an openingin the bolt end, an internally threaded ring adapted to be removablycarried by said sleeve and being provided with key-ways, extending partway around the same, and a key adapted to be passed through the slots ofthe sleeve, the key-ways of the ring and the opening in the bolt end,whereby said sleeve and said ring are removably secured in place.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
